I'll wait for the first reviews before praising. I wouldn't be surprised if the more complex design of the new caps introduces a light leak issue, which, as we all know, would ruin the day for a lot of lens cap shooters around here.

I'm going to weigh in... I do *not* like the pinch-type caps, I have some experience with the Tamron caps, and they were finicky, and I hit inside the filter threads all the time. I find the Canon caps more intuitive, because you're pretty much "fingering" the filter thread area when you put the Canon type cap on, whereas you're blindly aiming the Tamron pinch-type cap.

Also, I wanted to ask... why are folks putting caps on their lenses, with the hoods not reversed? What's the point? I can certainly see the desire to either a) leave the hood on, skip the cap or b) reverse hood, put cap on, but why have the hood + cap installed? Are you worried about dust with the hood on? If so, then why aren't you worried about covering the felt inner surface of the hood with dust while it's not reversed?

Discuss!

While I thought your point about guiding the cap on by feeling for the threads of the lens was quite valid, When I think about when i fiddle with lens caps its primarily to take them off. When I put them on i usually am reversing the hood to put in my case then attaching the cap. I imagine i may still put a couple fingers out to guide it or at least guide it based on fingers on the outside edge of the lens touching the rim of the lens. I do think having the pinch not come to close to the center would help for using it. If you are pinching too close to the center of the cap I can see my hands loosing a good feel for it. I'll probably buy 1 77mm cap to test it on my 24LII and 70-200LII before I buy into the whole thing.
